Excuse this extremely beginner question but earlier today I was making some iron sulfide and as the reaction proceeded there was a yellow gas being
evolved. I know it's not sulfur dioxide or hydrogen sulfide so what was it?

vapors of sulphur.

How about a complete lab description? I have NO IDEA what chemicals you used or how your process was conducted?

Sorry Bert, I mixed equal stoichiometric quantities of sulfur and iron filings. They were mixed thoroughly and put in a porcelain dish. The mixture
was heated by an alcohol flame until the sulfur melted. Heating was removed when the mixture began to glow. The mixture was cooled and collected until
testing could be done.

It's almost certainly airborne sulfur particles and vapors of sulfur.

Yep, sulfur. I remember seeing this stuff when I was working a blacksmithing forge that used genuine anthracite as a fuel source. We'd make so much
smoke that the archery range 100 feet upwind would complain of being blind.
